3 different 346xps and 2 262xps. The 346s are faster in this size wood. Honestly.... The 262s would pull 24" bar just fine. If your cutting 16"-18" wood, a ported 346xp is the ticket. I think they would even handle a 20" bar just fine. None of the saws are tuned through the roof, just work tunes. And of course, they all wear different chains. Not a scientific test, just fun with ported saws. All saws ported by mastermind.
